An atherectomy catheter directs particles generated by a cutting element into a collection chamber. A lumen configured to direct fluid into the tissue collection chamber.

Material removal device having improved material capture efficiency and methods of use

According to one aspect of the present invention, a fatigue resistant stent includes a flexible tubular structure having an inside diameter, an outside diameter, and a sidewall therebetween and having apertures extending through the sidewall. According to other aspects of the invention, processes for making a fatigue resistant stent are disclosed. According to further aspects of the invention, delivery systems for a fatigue resistant stent and methods of use are provided.

Implants having high fatigue resistance, implant delivery systems, and methods of use

A catheter which includes a cutting element having one or more raised elements is provided. The cutting element has a cup-shaped surface at the distal end that may be smooth and continuous except for the raised elements. The raised elements have a surface that tends to direct cut particles of material towards one or more of the axis of rotation of the cutting element, the catheter axis, or a particle collection chamber. In further aspects of the invention, a cutting element oscillates in a direction roughly parallel to the axis of rotation of the cutting element.

Device for cutting tissue

An atherectomy catheter directs particles generated by a cutting element into a collection chamber. A paddle attached to the cutting element propels fluid distally in the tissue collection chamber.

According to one aspect of the preset invention, a fatigue resistant stent includes a flexible tubular structure having an inside diameter, an outside diameter, and a sidewall therebetween and having apertures extending through the sidewall. According to other aspects of the invention, processes for making a fatigue resistant stent are disclosed. According to further aspects of the invention, delivery systems for a fatigue resistant stent and methods of use are provided.

An improved atherectomy catheter includes a part for propelling fluid distally in a tissue collection chamber. The part includes a drive shaft having a proximal end and a distal portion, and a propeller attached to the distal portion of the drive shaft.

The disclosure herein provides beneficial systems, methods, devices, and apparatuses that enhance and/or analyze images, and that can be configured to provide users an assessment and/or recommendation based on the enhanced and/or analyzed images. In an embodiment related to medicine, the assessment and/or recommendation is based on a patient situation, dimensions of patient organs/lumens, or the like in order to achieve personalized medicine.
